ROBUST AFFINE QUADRATIC STABILITY OUTPUT FEEDBACK CONTROLLER DESIGN

Vojtech Veselý - Mária Hypiusová - Igor Zvara

   The paper deals with the design of decentralized robust controllers with output feedback for a class of interconnected linear continuous time systems with parametric uncertainties. The uncertainties, in general nonlinear, can appear both in the subsystems as well as in their interconnections. No matching conditions or other similar constraints are to be considered in the complex uncertain system model. The proposed two approaches have been verified on a design of decentralized robust PI controllers using a non-iterative LMI based algorithm.

Keywords: decentralized control, robust control, linear matrix inequality, affine quadratic stability.
